The correct Answer is:
To determine how many oxygen atoms each chlorine atom is linked to in the compound \( Cl_2O_7 \), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Molecular Formula**: The molecular formula given is \( Cl_2O_7 \), which indicates that there are 2 chlorine (Cl) atoms and 7 oxygen (O) atoms in the molecule. 2. **Draw the Lewis Structure**: To understand how the chlorine and oxygen atoms are connected, we can draw the Lewis structure for \( Cl_2O_7 \). 3. **Analyze the Structure**: In the Lewis structure of \( Cl_2O_7 \), each chlorine atom is typically bonded to multiple oxygen atoms. 4. **Count the Bonds**: - Each chlorine atom is bonded to 4 oxygen atoms. - This can be visualized as each chlorine atom forming bonds with 4 oxygen atoms, including double bonds with some of them. 5. **Consider Shared Oxygen**: While each chlorine atom is bonded to 4 oxygen atoms, it is important to note that there is one oxygen atom that is shared between the two chlorine atoms. 6. **Conclusion**: Therefore, when we say how many oxygen atoms each chlorine atom is linked to, we find that each chlorine atom is linked to 4 oxygen atoms. ### Final Answer: In \( Cl_2O_7 \), each chlorine atom is linked to **4 oxygen atoms**. ---
